In 2015-2017, I remotely worked in a startup at the University of California at Berkeley (California, USA), which performed work on a grant from the U.S. Government.

I developed algorithms and C/C++ code for preparing models for 3D printing and milling. The work included the processing of 3D models with the formation of G-code for 3D printing and milling.

There were many options (more than 40) supporting:

• selection of 3D printing or milling;

• post-processing of the point cloud from the 3D scanner to correct the geometry of the model;

• definition of model topology and 3D fragmentation, using algorithms of Computer Vision (CV);

• CAD/CAM functions: cross-section in different planes and others;

• use of multiple extruders – T0, T1, ...;

• various algorithms of computational geometry;

• infill settings;

• definition of curvature;

• different ways of layering;

• import and export of 2D and 3D models STL, DXF, STEP and others.

The code was developed in Microsoft Visual Studio 2013 using third-party libraries: Cura, OpenMesh, DXFlib, GTEngine, Clipper lib, libArcus, Rapidjson, Protobuf. The intermediate results of calculations and transformations were viewed using utilities written in NetWars Engine. The final G-code was tested through the Autodesk Spark platform in a visual 3D-view.
